H. ANDREW AUTOMOBILE LOCK Filed Jan.5, 1926 2 Sheets-Sheet 2 'i eff 1i Y allofthelrings45, 46 and'4(- are formed .the slots`56 which, when properly positioned bythe lmob, willlreceive the lug 57 on 'i one ofthe members 19.-

In lorderto prevent the hublt with they f Fattachedl wheel, frombeing lifted bodily outJ l of the shell ll a ringkis employed to hold VAthe member 17 in'V its proper y position.

Gountersunk screws with 'lilled slots. are

fio

preferably provided for holding` this ringin position.v .In some 'instances itmay be prefserableto extend the hub'l outside of the shownin' Figure 2." A slight turn of'the :knob will now cause one ormore ofthe A rings i shell"T11"andl to fl'iave the ring 58`on the .undeiyside ofthe shellextending as v'far as f necessaryjtoward. the shaft lOto preventthe v`employn'ient of a clamp for uniting the steerling'-wlieel,ito the shaftfor driving/pur poses'. "These, however, ,are matters or con-v lstr y'ct-ion which may be'varied fromn in kde- `tail without departing' i this invention f c g t The operation ofthe device is as follows:

-fromthe spirit of assuming thatthe driver of a car wishes to rleave his machine so that it will not be-,used

b an one else hemoves-the handle 29 to J y i l the position shownfinFig'ure l whiclirauses all ofthe plungers 19 tobe withdrawn, as

45, ,46 orv47 to rotate; and` ifthis occurs even in a slightdegree it will be impossible to Aagain maire the ysteering wheel operable, l forcapable of steering the car vwithout a.

knowledge of the combination ofthe lock.

"i Vhenl the driver returnsto his .car it will be necessary forliiinto so manipulate the dial that all'V of the slots 56 ywill again be brought into register with the lug` 57. This Y is brought i. '40

about, for example as shown in the drawings, by first settingthemiddle ring 46, thentl'ie lowerrmg 47k and vthen the upper n ring 45. Obviously the operator has no way Y ofknowing which rthe different rings are or how? they operate, being,` only familiar with.

the. numbers on they dial andthe direction in `which the dial must be moved ni order to .bring about the desired results;

- .lVith the arms r'0, 52 anl 55and the lugs 4S, 49, 51, 53' and 54-positioned, shown, it

will-,be necessary for vhim yto .firsty turn the v dial tothe right to 5l, then left tov 54% and )their right lto 78, which again causes the f slots 56 to'register and to enable him to move the arm 28 and toengagethe ends 2O of the kplungers"19with the recesses 22. l l

'At first glanceV it may appear strange that only one lug 1s employed on the middle ring f plungers 46. This is due to the'fact that the middle l ring isv the basis of movement in this case, after which the next lower ring 1s positioned 'and' then the uppermost ring 45, somewhat l'. An automobile loclrr adaptedv to 'be placed. between the steering wheel and the steering wlieelshaft of an automobile, said look havingan outer shell adapted to rbe attached to a steering shaft; a hollow steering wheel hub rotatably mounted on said shell; a plurality of radial spokes slidably mounted in saidhub yadapted to vvproject therefrom and therebyeng'age said shell in a mannerv `to lock same to said hub; a cam for manually moving said plungers inwardly or outwardly; a lever for actuating said cam; a plurality Vof superimposed rings under said plunger concentric with and mounted in said hub; each ofsaid rings hava lug on one of'said plungers adapted to occupy all of said slots at onetime ,when in register in a manner that all of said plungers rotatably' l ing* ya slot formed inthe inner side thereof; r

can be projected from said hub, said rings having downwardly extending lugs formed thereon, each ring having ythe tipsof its lugs at a different elevation and radius than have'V the lugs of theother rings; a dialed stem passing through said hub; and a plurality of arms mounted on the lower end of said stem one for each ring, eacharmbeing adapted to engage the lugs of its ring; at the extreme end of each lug and arm.

2. An automobile lockL adapted to be` placed between the steering wheel and theVv steering wheel shaft of an automobile, said lock having an outer-shell adapted to be secured to said shaft; ahub forming a part'of the steering wheel, said hub having means for rotatably attaching sameto said'shell; a plurality of plungers radially mounted within said shell adapted to lock said hub to said shell when projected; a cam for moving said radially simultaneously; and means for locking said'cam against rotation.
